More precisely, the jump is: > ACPI-fast and TSC: -1.000000 +- 10 uS > i8254: -1.043000 +- 1 mS My nx6125 with F.11 BIOS does something very similar but only in VTY mode - I don't see the time jump when running X (and I haven't tried measuring the jump to that accuracy). Sometimes I see a time jump when switching between VTY and X. Other than that, ntpd is quite happy with ACPI-fast. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --8SdtHY/0P4yzaavF Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkhuuzAACgkQ/opHv/APuIe6EQCggVU8kzFpwaiJHTL5lxogAvfV OgMAoLEMs5k31pfmkous2gCL++7FFDSK =ACxk -----END PGP SIGNATURE----- --8SdtHY/0P4yzaavF--
